MLX90614 family
Single and Dual Zone
Infra Red Thermometer in TO-39
9 Unique Features
• The MLX90614 is a ready-to use low-cost non contact thermometer provided from Melexis with output
data linearly dependent on the object temperature with high accuracy and extended resolution.
• The high thermal stability of the MLX90614-xCx make this part highly suited in applications where
secondary heat sources can heat up the sensor. These sensors also have a very short stabilization
time compared to other types of thermopile sensors, which is of importance if one needs an accurate
measurement in conditions where the ambient temperature can change quickly.
• The MLX90614 supports versatile customization to a very wide range of temperatures, power supplies
and refresh rates.
• The user can program the internal object emissivity correction for objects with a low emissivity. An
embedded error checking and correction mechanism provides high memory reliability.
• The sensors are housed in an industry standard TO39 package for both single- and dual-zone IR
thermometers. The thermometer is available in automotive grade and can use two different packages
for wider applications’ coverage.
• The low power consumption during operation and the low current draw during sleep mode make the
thermometer ideally suited for handheld mobile applications.
• The digital sensor interface can be either a power-up-and-measure PWM or an enhanced access
SMBus compatible protocol. Systems with more than 100 devices can be built with only two signal
lines. Dual zone non contact temperature measurements are available via a single line (extended
PWM).
• A build-in thermal relay function further extends the easy implementation of wide variety of
freezing/boiling prevention and alert systems, as well as thermostats (no MCU is needed).
